Full disclosure up front - I'm not a gunsmith (as you will see from my question). I'm hoping to tap into the experience of you guys who are by asking your reaction to the article in the current issue of Rifle Magazine on heat-treating barrels. The article was the first thing I read in this issue - the title grabbed my attention. Some interesting claims were made relative to the various rifling methods, which I had heard before. However, the author made some statements which he appears to support with pictures of target groups which, to my eye at least, were not super impressive. I'd sure be curious to hear reactions from those of you who have read the article - or - who have had experience of heat treating finished (i.e. already rifled) barrels.
